The invention relates to a concrete building construction and more especially to a system of,

building construction using precast concrete units.

The primary object of the invention is the provision of a building construction of this character, wherein through the use of precast concrete units, these being in the form of slabs which by their shape and dimension under assembly form walls and roofs with air spaces and at the same time permit placement of reinforcing steel either plain or fabricated and the pouring of concrete to provide a continuously reinforced structure of any height and involving one or more stories.

Another object of the invention is the provision of a building construction of this character, wherein through the use of the precast units economy of material is assured and likewise labor, quickness of erection, fireproof and having a very low cost of maintenance, permitting the easy placement of a wall finish'like Celotex, sheet rock or similar material as a furring may be placed between the units and such material as just mentioned nailed thereon.

A further object of the invention is the provision of a building construction of this character, wherein a monolithic reinforced edifice is attained with a continuity of arrangement and with a thickness to such edifice in its walls and fiooring for sustaining loads or weights and in the erection eliminates any necessity for alteration in the slabs or units as to-the shape, weight and volume thereof.

A still further object of the invention is the provision of a building construction of this character, wherein monolithic characteristics thereof with a continued succession in erection and in the use of precast units or slabs, these in the assembly allow cavities for casting structural columns in the corners or unions of walls in their various distribution and such erection does not require skilled labor as the units or slabs can be quickly brought to place without much trouble and without using timber props at all.

A still further object of the invention is the provision of a building construction of this character, wherein there is involved refinements, over the subject matter of United States Letters Patent No. 2,001,696 issued May 21, 1935, the construction being reinforced and susceptible of withstanding weather changes, possessed of strength and durability and inexpensive to erect.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto appended.

Referring to the drawings in detail, the reinforced concrete construction comprises a foundation including the required number of precast horizontally arranged blocks III which when-end to end serve as beams or sills and are leveled and supported directly on the ground or' by means of a sub-base of any adequate material and the same may be rod reinforced. These sills or beams are joined in any suitable manner and being arranged with relation to each other according to the desired framing of an edifice.

Formed in the upper faces of the blocks I0 are channels or grooves H, the sides I2 being disposed in upwardly divergent relation to each other and into these channels or grooves II are fitted the lower ends of precast slabs or units l3 and I4, respectively, the latter forming themside wall while the former the outside wall of the edifice. These slabs or units l3 and M are similar to each other and have formed at their innermost faces substantially rectangular frame-like flanges IS with reversely beveled or angled faces 16 and I1, respectively, the flange l5 on each slab at one end of the latter being removed from that end next thereto to provide a beam recess l8. These slabs l3 and I4 are arranged side by side with the flanges l5 confronting each other, the latter being joined by a plastic bonding l9 and thus there is provided between said slabs an air chamber or space 20. The inner faces of the slabs l3 and M are formed with the longitudinal and transverse brace ribs 2| within the framelike flanges I5 while embedded in said slabsare longitudinal and transversely disposed reinforcing rods,22 and 23, respectively.

At a comer of an edifice and at a dividing wall as may be provided therein the slabs l3 and M in association with corner angle precast concrete pieces 24 and outside facing pieces 25, respectively, eifect spaces for the pouring of cementitious or concrete columns 26 and 21, respectively, these having embedded therein rod reinforcements 28, the reinforcements 28 extending longitudinally of such columns being extended into the sills or beams constituting the foundation l0 and such beams fit the reversely beveled sides l6 of the slabs l3 and M as is clearly shown in Figures '7 and 8 of the drawings.

The flanges l5 at the longitudinal sides of the slabs l3 and M are provided with holes or passages 29 for accommodating tie or anchoring elements 30, these being set in fillings 3| poured between the reversely beveled faces l6 of the side edges of said slabs l3 and I4 as is clearly shown in Figure4 of the drawings and such elements are loose within the passages of holes 29 so as to allow for expansion and contraction of the walls of the edifice according to the changes of weather elements.

The flanges I5 at the longitudinal sides of said slabs l3 and it have embedded therein rod re-.

inforcements 32 which extend into the recesses l8 and into these recesses is poured cementitious material or concrete to provide horizontal beams 33, the latter also being provided with metallic reinforcements 34.

Corelated with the walls constituted by the slabs l3 and H are the precast concrete ceiling and fioor slabs 35 and 36, respectively. The cellto constitute the walls, both outside and dividing walls, are joined with the sills in the grooves or channels II with cementitious fillings 43 located between-the sides 12 andthe outer faces of said slabs l3 and M, respectively.

The fillings 3| carry reinforcing rods 44 which may continue throughout such fillings in a ver ticaldirection between the inner and outer slabs l3 and I4.

Under the construction described there is obtained a truly monolithic edifice of fully reinforced concrete, the reinforcenients of which is continuous notwithstanding the fact that there is used the precast slabs or units in the erection of the edifice. The embedded reinforcements in the respective fillings and beams will project into the columns and thus the entire edifice is unitary, the slabs 36 being also serviceable as roofing.
